I'm doing good so far on leads to follow up on with my other posts, so here is another. I only have one of these shades, beautiful glass, first though to be a Vaseline shade, but I haven't had the chance to check with the black light. It was amongst the other Steuben, Quezal and Tiffany shades which were in sets of 3 or 4. Unfortunately Grandma cant remember how or where she acquired it.
